A, The development of sedentary time (ST), light physical activity (LPA), moderate to vigorous physical activity (MVPA), and vigorous physical activity (VPA) during the follow‐up for the whole week (Total), weekdays (WD), and weekends (WE) in boys (●) and girls (▲). The dotted lines represent the mean growth curves in boys and girls (estimated by using the parameters of the linear growth curve model). B, The development of sedentary time (ST), light physical activity (LPA), moderate to vigorous physical activity (MVPA), and vigorous physical activity (VPA) during the follow‐up for weekdays (WD) in boys (●) and girls (▲). The dotted lines represent the mean growth curves in boys and girls (estimated by using the parameters of the linear growth curve model). The weekdays (WD) are further divided into school time and leisure time based on the pupils’ individual curricula
